Glass Type Question
I was given a bunch of shorts and odd glass rods from a friend who SWEARS he never used boro. But some of them, a clear and a dark blue so far, are just as stiff as can be when melted....I tried the clear with one of my 104 glass colors and the bead just crumbled after I took it out of the kiln.
Would Bullseye be a stiffer glass than 104? If they're not labelled is there any way to tell them apart?
Thanks much, Julie

Bullseye is slightly stiffer, and some of the opaque colors have a bit of transluence to them. Bullseye is also more regular (from what I've seen) in rod size. You can check the Bullseye site for a color reference.
Boro melts WAY brighter than either, and takes a while to melt also.
You can melt the glass with something that you're sure is 104 and pull a stringer to see if it stays straight or not - bent or curved shows incompatibility.

Crumbling probably means that it is boro. BE and 104 usually crack - boro and soft glass crumble.
A lot of soft glass people use clear boro punties and cobalt boro for fuming. Perhaps that is why they are in there.

EXACTLY what I was going to say! If it doesn't act right, it's probably not right.

If your eyes hurt from the soda flare after melting the cane (assuming you are wearing soft glass eye protection) - it's boro.

Hmmm....some stuff to check out. Thank you everyone!
I have some boro (sample pack that came with my torch), and it took forever to melt it on my little mini cc...so I don't think it's boro.
I don't remember how bright it was. I know it melted stiffer and weirder....it might have been brighter too...but it wasn't too bad...
I'll try the stringer trick. Never heard of that and had to think about it for a minute...lol. but i get it.
Thanks!
Julie
